What This Plugin Adds

Section titled “What This Plugin Adds”

Agent Bridge is an Available, Schema-owning Capell package in the Capell AI product group. It ships as capell-app/agent-bridge and extends these surfaces: admin, frontend.

Agent Bridge connects MCP clients to read-only Capell knowledge and a frozen, draft-only site capability contract over per-user HTTP and explicit-user local stdio, with preview confirmation and redacted audit records.

Admins can build scoped prompts and manage a user’s client tokens, confirmations, and audit entries. Connected clients can call only the server routes and capabilities enabled for them.

Status details:

  • Status: Available
  • Tier: premium
  • Bundle: ai
  • Composer package: capell-app/agent-bridge
  • Namespace: Capell\AgentBridge
  • Theme key: not applicable

Why It Matters

Section titled “Why It Matters”

For developers: Capability providers register typed operations through CapellAgentBridgeCapabilityProvider, contribute their own deterministic direct-command patterns alongside them, and mutating runs pass through preview, confirmation, policy, and audit Actions.

For teams: Agent Bridge is the governed AI connection for Capell: the connected AI client supplies the reasoning, while Agent Bridge limits an agent to approved capabilities, shows a proposed change before execution, and records what each client ran.

Data Model

  • Migration impact: run host migrations through the package install flow before opening package surfaces.
  • Deletion/retention behaviour: migrations declare cascade-on-delete relationships and null-on-delete relationships; retention is scheduled through capell:agent-bridge-prune-audit (daily; declared in the manifest).

Install Impact

Section titled “Install Impact”
  • Required packages: capell-app/admin, capell-app/core.
  • Admin navigation: declares admin-page: AgentBridgeAdminPageContribution; each Filament page or resource controls its own navigation visibility.
  • Admin/editor extensions: schema-extender: AgentBridgeUserSchemaExtenderContribution.
  • Permissions: agent-bridge.manage-tokens, agent-bridge.view-audit.
  • Public routes: loads routes/agent-bridge.php; registers AgentBridgeRoutesContribution.
  • Database changes: package migrations are declared.
  • Config: config/capell-agent-bridge.php.
  • Settings: Capell\AgentBridge\Settings\AgentBridgeSettings.
  • Queues or schedules: scheduled commands capell:agent-bridge-prune-audit (daily; manifest declared).
  • Cache tags: none declared.
  • Commands: capell:agent-bridge-prune-audit.

Common Pitfalls

Section titled “Common Pitfalls”
  • Keep required Capell packages on compatible v4 releases: capell-app/admin, capell-app/core.
  • Run migrations before opening package resources or public routes.
  • Review package configuration before production-like verification: config/capell-agent-bridge.php, Capell\AgentBridge\Settings\AgentBridgeSettings.
  • Review middleware, throttling, signatures, and public-output safety in routes/agent-bridge.php before exposing routes.
  • Keep the host Laravel scheduler running so package-registered schedules can execute: capell:agent-bridge-prune-audit (daily; manifest declared).
  • Keep public Blade and cached HTML free of authoring markers, model IDs, permissions, signed editor URLs, and lazy database queries.

Troubleshooting

Section titled “Troubleshooting”

Quick Start

Section titled “Quick Start”
